Testing Multiple Conceptualizations of Oppositional Defiant Disorder in Youth

Area of Science:

• Child and Adolescent Psychiatry
• Psychology
• Behavioral Science

Background:

• Oppositional defiant disorder (ODD) is increasingly conceptualized as a two-dimensional construct.
• These dimensions include affective (angry/irritable) and behavioral (argumentative/defiant) components.
• Previous research supported this view in nonreferred youth, but not in clinic-referred populations.

Purpose of the Study:

• To examine multidimensional conceptualizations of ODD in clinic-referred youth.
• To assess treatment-related improvements across ODD dimensions.
• To determine if improvements in ODD dimensions predict clinical outcomes.

Main Methods:

• Reanalysis of data from 134 clinic-referred youth (ages 7-14) with ODD receiving psychosocial treatment.
• Assessment of ODD symptoms, aggression, conduct problems, and clinical impairment at pretreatment, 1-week, and 6-month follow-ups.
• Testing of one- and two-factor ODD models using baseline symptom data.

Main Results:

• Both one- and two-factor ODD conceptualizations were supported, with the two-factor model being preferred.
• Significant and similar improvements were observed across both affective and behavioral ODD dimensions.
• Improvements in both ODD dimensions significantly predicted clinician- and mother-reported clinical outcomes.

Conclusions:

• The findings support the two-dimensional, multidimensional conceptualization of ODD in clinic-referred youth.
• Treatment interventions should consider both affective and behavioral components of ODD for improved outcomes.
• Further research into multidimensional ODD models is warranted for clinical populations.
